TWB728 was operating from RKSS to RKSI on 2025-12-17. SkyMeter detected a long landing rollout at Incheon International Airport (RKSI) on runway 33R at 12:51 UTC. Trace data at the event: 32 ft AGL, 22 kt GS, 0 fpm vertical. Approach stability score: 49/100. Scores below 50 occur on under 10% of approaches at this runway and indicate the v2 scorer flagged the approach as highly anomalous (three or more gates exceeded the runway's P90 envelope simultaneously). METAR at the time reported 3 kt wind, 9,994 m visibility. A long landing rollout is detected when ground deceleration after touchdown is below the per-runway P10 envelope. It is an observational measure of rollout efficiency, not a runway-exit incident. Detection algorithm and known limitations: see SkyMeter methodology.

Automated analysis. Events shown on this page (such as go-around, unstable approach, or runway events) are heuristic classifications produced by algorithms from publicly broadcast ADS-B data. They are intended to surface flights of interest for further review — they are not findings of fact, and they do not determine pilot fault, regulatory compliance, or the cause of any occurrence. Coverage gaps and sensor noise can affect accuracy. Only the relevant civil aviation authority or accident investigation body can make official determinations.
